2002 S10 extreme 4.3 drove home ok now it wont start no spark need help

A lot of things can cause a no spark. The most common would be the crankshaft sensor, the ignition coil, or the ignition control module. These can be tested at an auto parts store, so your not just buying parts to try. Also look at the underneath side of the rotor to see if there is a burn mark. If there is then the spark is going to ground right there.
